# Guidance Navigation and Control (GNC)

**R-2A activity** of project 3095 — Nuclear Delivery Systems  
**Program element:** 0603273N — Science & Technology for Nuclear Re-entry Systems  
**Component:** U.S. Navy · **Budget Activity:** 3  
**Vintage:** President's Budget PB2027

## Summary

This activity requests $64.1M in FY2027, 56% of project 3095, down 12% on FY2026. The R-2A exhibit describes it across FY2026–FY2027, including what the FY2027 money is planned to buy.

## What the FY2027 request buys

**FY2027 planned work.** - Continue development of an accelerometer that can handle higher g-loading - Continue development of a radiation hardened inertial measurement unit (IMU) - Continue development of a radiation hardened flight computer - Continue development of navigation aids for challenging environments - Continue advanced hardened actuator development - Continue attitude control system (ACS) development - Further information can be provided at a higher classification level

**FY2026 to FY2027 change.** The $8.48 million decrease from FY 2026 to FY 2027 is a result of the program's strategic phasing. FY 2026 funding supports the majority of the preparatory work for the integrated aeroshell and GN&C demonstration, while the reduced FY 2027 budget covers the demonstration's execution.

## Before the request year

**FY2026 plans — current year.** - Continue development of an accelerometer that can handle higher g-loading - Continue development of a radiation hardened inertial measurement unit (IMU) - Continue development of a radiation hardened flight computer - Continue development of navigation aids for challenging environments - Begin advanced hardened actuator development - Continue attitude control system (ACS) development - Further information can be provided at a higher classification level

## Funding

| Fiscal Year | Estimate Type | Amount ($M) |
|---|---|---|
| FY2025 | Actual | 66.3 |
| FY2026 | Enacted | 72.5 |
| FY2027 | Request | 64.1 |

> Prior, current and budget year only — an R-2A activity carries no five-year plan. It sums exactly into its project in the request year and not necessarily in any other.
